Abstract
A computer-implemented method, according to one approach, is for detecting ransomware activity in storage systems. The computer-implemented method includes: receiving a write request having a plurality of sectors, and each of the sectors further includes a number of sub-sectors. A degree of randomness is determined across the sub-sectors of each of the respective sectors, and a determination is made as to whether any deviations exist in the degrees of randomness. In response to determining a deviation exists in the degrees of randomness, this information on the deviation is used as an indicator of the write request including ransomware activity.
